adaptec aha-2940

This should be in a FAQ: there is no support for any Adaptec AHA-2xxx series
controller. It would be great if someone wrote a driver since these are popular
and show up embedded on motherboards. However, it's completely different from
any other Adaptec controller and I've been convinced by others on the list that
a driver would be a fair amount of work. A month or so ago this was my response:


    None that I know of. Someone should probably do it as the Adaptec 2xxx controllers
    are fairly popular. However, it's unlikely to be me as
	1) I tried again to get the manuals only to receive the "User's Guide"
	   like I did 2 years ago and on further inquiry discover the useful
	   manuals are all on back-order;
	2) I don't have a controller and they do seem rather expensive compared
	   to the NCR8xx alternatives with similar performance;
	3) I looked at the Linux driver after this question came up last time
	   and got frightened.

Hi,

We have a few Gateway machines with Adaptec AHA-2940 PCI SCSI Master
controllers.  So far as I can tell, Plan9 doesn''t seem to be happily
recognizing them.  Can anybody give me any advice on where to go from
here?  I'm willing to spend up to say 5*20 hours writing a device
driver (Mountain Dew, yummy) if that is the best route.  Advice as to
which parts of the source I can cut and paste, potential similarities
with say the 1542, etc etc would be much appreciated.  Thanks.

Please reply via e-mail and through the newsgroup (just in case our
newsreader chokes),
